For fans who have been clamoring for it for years, this represents a potentially exciting change. But the question remains: do the Giants have the right personnel for a switch from 4-3 to 3-4?

Damon Harrison and Dalvin Tomlinson serving as nose tackles is an obvious fit, but what about defensive ends Jason Pierre-Paul and, more specifically, Olivier Vernon?

Retired Arizona Cardinals head coach Bruce Arians, who is a public supporter of Bettcher, believes with only a few adjustments, the Giants could make the change with ease. And for someone like JPP, the switch to outside linebacker would come naturally.

In fact, Arians is so confident about that, he attempted to get Pierre-Paul under contract in 2015 before Arizona acquired Chandler Jones from the New England Patriots.

“Heck yeah, we really went after him,” Arians told NJ Advance Media. “What [Bettcher] did with Chandler Jones was amazing. You drop into coverage some, but the majority of the time you’re rushing the passer.”

And Vernon?

“[Bettcher will] find a spot for them,” Arians said. “Nickel defense is 70 percent of the game anyway, so they’re going to be playing a 4-2 anyway. They’ll be put in their natural position. It gives them a position to grow into and get more sacks.”

Adrians also believes safety Landon Collins, who is already one of the league’s best, will also thrive under Bettcher.

“I think he’s perfect,” Arians said. “What [Bettcher] did with Tyrann Mathieu and then this year with Budda Baker [and] Antoine Bethea had five picks this year. So, the safety role is so versatile and you’ve got a guy that’s a versatile player. What Tyrann has done from that position, Landon is perfect for.”

For his part, Shurmur hasn’t dismissed the idea that a switch to 3-4 is coming, and went as far as to suggest most of the defensive linemen could convert.

“Some of our defensive linemen can convert,” Shurmur said. “It’s five on the line, but it’s one gap. So whether it’s four on the line or five on the line, you’re playing one-gap defense. They all do that.”
